Health, these stories are indeed true and it is very common among yeshivas for both boys and girls. This is a “blind” attitude and it is one that “SHOVES” children off the derech without rachmanus. Kids are thrown out of yeshiva and off unto the streets without warning for such an infraction. The punishment does not fit the crime, especially at the end of a school year, especially for a senior, for an excellent student in both midos and grades.
The Rosh Yeshiva should have A) Told the Yenta that he does NOT listen to Loshan Horah B) She is not permitted to Masser C) Asked the Bochur what the circumstances were surrounding the incident and then explained why HE thought it was wrong especially since he had an exemplary record.
